Amazon EC2 Plugin connects to Windows agents via HTTPS.
Amazon EC2 Plugin 1.50.1 and earlier unconditionally accepts self-signed HTTPS certificates and does not perform hostname validation when connecting to Windows agents. This lack of validation could be abused using a man-in-the-middle attack to intercept these connections to build agents.
Amazon EC2 Plugin 1.50.2 by default no longer accepts self-signed HTTPS certificates and performs hostname validation. A new configuration option allows restoring the previous, unsafe behavior. For more information see the plugin documentation.
